Pro-96 - The RadioReference Wiki
Yes, it appears that it is capable of monitoring the RWC (Phoenix Regional Fire, Chandler PD, Tempe PD, etc) as well as the TOPAZ RWC (Mesa Regional Fire which dispatches Queen Creek 410-series units, Mesa/Gilbert/Apache Junction PD's).
Whether you have any simulcast multi-path interference issues common to the RWC/TOPAZ RWC reception is another question.
Mesa FD is also using analog conventional VHF, at least for dispatch. There's another thread here about future plans to expand their use of VHF.
You should also be able to receive the YRCS trunked system, which carries ADOT communications, including ALERT units (traffic control specialists who respond to incidents on the freeways when extended restrictions or closures need to be put into place) and the Enforcement and Compliance Division officers (commercial vehicle enforcement).
Maricopa County DOT has a REACT unit which is similar to ADOT's ALERT unit, but works with MCSO and munincipal PD's and FD's on road closures. They've also worked with ALERT when traffic diverted off the freeway needs to follow a specific surface street route around the closure and back on the freeway. They're on the county's trunked system, TG 912.
Rural-Metro Fire 840-series units cover the neighboring San Tan Valley area, and stations 857 & 859 cover county islands in the Mesa area, on their analog conventional VHF channels.
DPS is on analog conventional UHF. Metro East and Metro East Tac covers the I-10, 60, 24, 87, and 202 freeways. CI 1 & (especially) 2 and Statewide & State Tac are also worthwhile to have. (The Metro and Metro Tac channels are also capable of being simulcasted on the YRCS, but I haven't heard them active in many months.)
You should be able to hear Coolidge and Florence FD and PD's on analog conventional VHF, and Gila River FD on analog conventional 800 MHz if you want to. (Gila River PD is encrypted.)
